Hunger as a Catalyst in Aggression

Abstract

AbstractUnder thermal conditions of 90° F 50% RH and a subject density of I subject per 0.125 sq. ft, two strains of inbred mice, C-57 (aggressive) and A/J (docile) were tested for aggressive behaviour following food deprivation periods of 0, 24, 36, and 48 hours. The greatest amount of aggression occurred in the 24 hours deprivation group of C-57 subjects whereas the 36 hour hungry A/J animals were most aggressive. Metabolism as evidenced by activity level and extent of food deprivation is suggested as the primary determinant of aggressive behaviour when temperature and subject-density are held constant.
